The Akrapovič Slip-On system is based on the same layout as the original exhaust system of the GT3 with valve control. The Slip-On contains a titanium muffler with two double round tailpipes. The muffler is easily installed on the original exhaust system. The Akrapovič Slip-On makes the GT3 more powerful and lighter, even though the exhaust system is not replaced entirely. The sound of its six-valve engine is also noticeably improved. The Slip-On exhaust system offers weight reduction in the rear of the Porsche and an increase in power. Two tailpipes, 100 mm in diameter, make it clear that the Akrapovič Slip-On system is no ordinary exhaust.
